Ketamine-Assisted Psychotherapy for Depression: What to Expect at Somatic Psychotherapy Center
Ketamine-assisted psychotherapy for depression offers a different kind of entry point for people living with depression. At Somatic Psychotherapy Center, we use KAP as part of a larger course of therapy: one that’s relational, body-based, and tailored to where you actually are. Whether you’ve tried other treatments and found them incomplete, or you’re simply curious about what this approach offers, you’ll find more information in this post.
Depression can feel like living behind glass. You can see your life, the relationships, the work, the things that used to matter, but you can’t quite reach them. You go through the motions. Maybe you’ve been in therapy before, or tried medication, or both. And still, something stays stuck.
Ketamine Assisted Psychotherapy (KAP) treats ketamine not only as a medication that can help with a wide range of mental health symptoms, but also as a catalyst that can make the therapeutic work deeper and more available to you. That distinction shapes everything about how we practice.
What Makes Ketamine-Assisted Psychotherapy for Depression Different
Most people have heard of ketamine as an anesthetic, or more recently as a treatment for depression or anxiety available through infusion clinics. What’s less widely understood is the difference between ketamine infusion therapy and ketamine-assisted psychotherapy.
Ketamine infusion clinics typically administer the medication in a medical setting, monitor your vitals, and send you home. The focus is pharmacological: ketamine as a drug that acts on the brain. And it does act on the brain, meaningfully. But Ketamine Assisted Psychotherapy treats ketamine as both a medicine and an experience, one with therapeutic potential that extends well beyond its chemical effects.
In ketamine-assisted psychotherapy for depression, the medicine session unfolds within a therapeutic container. A trained therapist attends throughout, attuned to what’s arising for you. The subjective experience of ketamine can include shifts in perspective, a loosening of habitual thought patterns, and a felt sense of spaciousness. That experience becomes material for the therapy itself. You and your therapist can explore and integrate what surfaces during the subjective experience before, during, and after.
This distinction matters because depression isn’t only a neurological condition. It lives in the body, in patterns of self-relation, in the stories we’ve absorbed about who we are and what we deserve. Treating it requires more than a medication. It requires a relationship, and it requires integration.
How Ketamine Works: The Science Behind KAP for Depression
To understand why Ketamine Assisted Psychotherapy can be so effective for depression, it helps to know a little about the underlying biology.
Most antidepressants work on serotonin or norepinephrine systems and take weeks to build up therapeutic effect. Ketamine works differently. It acts on the glutamate system, triggering a rapid release of brain-derived neurotrophic factor (BDNF), a protein that supports the growth and repair of neural connections. Research published in Biological Psychiatry has shown that this process, called neuroplasticity, can produce antidepressant effects within hours rather than weeks.
What this means practically is that ketamine opens a window. The brain becomes more flexible, more receptive to new patterns and experiences. Synaptic connections that depression has worn into grooves of hopelessness or self-criticism become temporarily more malleable.
The Polyvagal Institute and researchers in the somatic field have noted that this window of neuroplasticity is also a window of somatic openness. The body, not just the mind, becomes more available to new experience. At Somatic Psychotherapy Center, this is exactly where the therapeutic work happens. The medicine session isn’t a passive experience. It’s an invitation to meet what’s been frozen, to notice what the body holds, and to begin, slowly, to let it move.
What KAP Looks Like at Somatic Psychotherapy Center
Many KAP providers approach the medicine session as a largely interior experience. You lie down, put on an eye mask, listen to music, and report back afterward. We do this too. But the relational and somatic dimensions of our approach shape every phase of the process.
KAP at SPC unfolds across three phases.
Preparation: The First Phase of KAP for Depression
Before the medicine enters the picture, you and your therapist spend time getting to know each other. You’ll explore what’s brought you to this work and set intentions together. For depression specifically, we often work with questions like: Where do you feel the heaviness in your body? What does the depression protect you from feeling? What small openings have you noticed, even in difficult periods? This isn’t intellectual preparation alone; it’s also somatic and slo relational. You’re beginning to build a relationship with your own inner landscape and a sense of safety with your therapist before the medicine ever enters the room.
The KAP Medicine Session: What to Expect
Sessions take place in a comfortable, carefully designed office space, not a clinical infusion suite. You recline, use an eye mask and headphones if that supports your experience, and settle in. We work with a Nurse Practitioner who conducts a separate intake to prescribe ketamine lozenges that dissolve under your tongue. Your therapist remains present throughout, tracking your nervous system and available for quiet support. Ketamine-assisted psychotherapy for depression at SPC unfolds relationally, meaning your therapist isn’t just monitoring. Your therapist is with you. If something difficult arises, you’re not alone in it.
Integration: Completing the KAP Process
This is where much of the lasting change happens. In the days and weeks following a medicine session, your therapist supports you in making meaning of what arose, connecting it to your therapeutic goals, and bringing the body back into regulation as the neuroplasticity window gradually closes. Integration might involve somatic tracking, IFS parts work, or simply sitting with what opened up and letting it settle.
We also offer group KAP sessions for those who want to do this work in community. Group KAP can be a powerful complement to individual sessions, offering the added dimension of shared experience and relational witnessing.
Who Is a Good Candidate for KAP for Depression?
Ketamine-assisted psychotherapy for depression suits a wide range of people. You don’t need to have exhausted every other option, though many of our clients come to KAP after finding that antidepressants or traditional talk therapy haven’t provided the relief they were hoping for.
Good candidates bring motivation for inner work and curiosity about going deeper, readiness to engage the body as part of healing, and a desire for therapeutic relationship rather than just a medical procedure. Because the medicine can bring up unexpected emotional content, a sense of trust and safety with your therapist is essential. That’s one reason we invest heavily in the preparation phase.
KAP is not appropriate for everyone. People with certain psychiatric histories, including active psychosis or mania, are typically not good candidates. A thorough intake process and coordination with a prescribing provider help ensure that KAP is the right fit before any medicine session begins.
The Somatic Dimension of KAP for Depression
Depression often lives below the level of thought. It’s the heaviness in the chest that’s there before you open your eyes in the morning. The flatness that settles in the belly. The way the body seems to slow and contract, as if bracing against something.
Somatic Experiencing, Internal Family Systems, and other body-based modalities recognize that healing depression isn’t only about changing what you think. It’s about helping the body complete what it’s been holding, and learning what safety and aliveness feel like from the inside. You can read more about the body’s role in depression and how somatic approaches address what talk therapy often can’t reach.
Ketamine-assisted psychotherapy for depression pairs especially well with somatic therapy for depression because the medicine can lower the body’s habitual defenses. The chronic bracing softens. Parts of the self that have been hidden become more accessible. Clients often describe the experience as a loosening, not a fixing, but a kind of opening that makes the therapeutic work more available.
This is the heart of what we offer at SPC: not ketamine as a cure, but ketamine as a doorway, and a therapist who’s trained to walk through it with you.
Frequently Asked Questions About Ketamine-Assisted Psychotherapy for Depression
What is ketamine-assisted psychotherapy for depression?
Ketamine-assisted psychotherapy for depression combines ketamine medicine with active psychotherapy before, during, and after the medicine session. Unlike standalone ketamine infusions, KAP focuses on the therapeutic and experiential dimensions of the medicine, using the neuroplasticity window it creates to support deeper psychological and somatic healing. At SPC, our approach is relational and body-based throughout.
How is KAP different from ketamine infusion therapy?
Ketamine infusion therapy treats ketamine primarily as a medication, with clinical monitoring in a medical setting. KAP treats the medicine session as a therapeutic event, with a trained therapist present throughout. The subjective experience of the medicine, and what it brings up emotionally and somatically, becomes part of the therapeutic work. Learn more about what to expect from KAP.
Who is a good candidate for KAP for depression?
KAP for depression works well for people who bring motivation for inner work, openness to body-based healing, and a desire for relational therapeutic experience. It helps those who haven’t found relief through antidepressants or talk therapy alone, as well as those newer to treatment who want a depth-oriented approach from the start. A thorough intake process helps determine whether KAP fits your specific situation and history.
What does a ketamine-assisted psychotherapy session look like?
At SPC, KAP sessions take place in a warm, comfortable office space. You recline and may use an eye mask and headphones. Your therapist attends throughout, attuned to your nervous system and available for support if needed. Sessions typically last three hours. Preparation work comes before the medicine session, and integration sessions follow, where you process what arose and connect it to your broader therapeutic goals.
How many KAP sessions does depression treatment require?
Most KAP protocols for depression involve a series of medicine sessions, often two to three to start, alongside ongoing preparation and integration work. The number that’s right for you depends on your history, goals, and how you respond to the initial sessions. We find that KAP proves most effective when it’s embedded in a larger course of therapy rather than serving as a standalone intervention.
